Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 250 Issued at 2200Z on 07 Sep 2006

IA. Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity was very low. Region 909 (S09E09) produced a long duration B4.2 flare at 07/0746 UTC. No new regions were numbered today.
IB. Solar Activity Forecast: Solar activity is expected to be very low with a slight chance for an isolated C-flare.
IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z:
The geomagnetic field was quiet with an isolated active period at middle latitudes between 07/0600 - 0900 UTC. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels again today.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet.
